This knife is an EDC due to a boogered pivot torx (too tight for customer to loosen).    Picture is stock, not actual knife.

    I really couldn’t be happier with this little Italian gem. The size, quality, the gray oak handles are all amazing. And the wharncliffe blade is stunning. Nice stout pull, smooth and lined up all over. This is my second purchase from CK’s modern traditional offerings, and first from Viper. It is just a beautiful little knife, probably have actually cut something with it 3 times, and pulled it out to fidget 300. This was discounted as EDC for minor flaw and it is indeed minor. Functions perfectly and looks great.
